I. Core Overview of the Product

II. Core Uses and Application Scenarios

1.Water treatment field (core application)

• Drinking water purification: Efficiently removes residual chlorine, heavy metals (lead ≤ 200ppb, mercury ≤ 10ppb, etc.), organic substances and odors. It is the preferred material for water purifier filters, waterworks, and bottled water production.
  
  
  Industrial wastewater treatment: Adsorbs dyes, oils, and chemical pollutants. The COD removal rate exceeds 80%, suitable for industries such as chemical engineering, printing and dyeing, and papermaking.
  
  
  Special for chlorine removal: The free chlorine removal rate of LC type reaches 99-100%, suitable for advanced treatment of water purification equipment.

2. Gold extraction

3. Air purification and waste gas treatment

• Indoor formaldehyde removal: For newly decorated houses, use 50g per square meter to quickly absorb formaldehyde, benzene, ammonia and other VOCs.
  
  
  Industrial waste gas treatment: Adsorb harmful gases such as hydrogen sulfide and chlorine from chemical plants and leather factories, with a purification efficiency of ≥90%.
  
  
  Gas masks / air conditioning filters: Remove toxic gases and odors to ensure the safety of confined environments.

4. Food, Medicine and Chemical Industry

• Decolorization and deodorization: refining of wines, beverages, monosodium glutamate, and citric acid to improve product purity and taste
  
  
  Catalytic carrier: serving as a catalyst carrier for vinyl acetate to support chemical synthesis reactions
  
  
  Solvent recovery: adsorbing volatile solvents such as gasoline and acetone to realize resource recycling and reuse

5、Product Advantages and Selling Points

6、Packaging and Storage

1. Standard packaging

• 25kg/bag: Laminated woven bag + PE inner bag, moisture-proof and anti-pollution
• 
• 
  
  500kg/1000kg/bag: Ton bag, suitable for industrial bulk purchasing
• 
  
• 
  Custom packaging: Can print company LOGO and product information, in line with export packaging standards

2. Storage requirements

• Store in a dry and well-ventilated warehouse, and avoid water immersion (water immersion will block the pores and lose the adsorption capacity).
  
  
  Keep away from fire sources and tar-like substances, and the storage temperature should be ≤ 35℃.
  
  
  During transportation, avoid mixing with hard objects to prevent carbon particles from breaking.

7、Usage Notes

1. Transportation: Handle with light loading and unloading, avoid severe collisions, and prevent particle breakage from affecting strength.
   
   
   Usage: For newly renovated houses, apply 50g per square meter and replace every 30 days; for water treatment equipment, install with a filling rate of 10-20%.
   
   
   Regeneration: During regeneration, cool to below 80°C before contacting oxygen to prevent spontaneous combustion.
   
   
   Taboos: It is forbidden to contact tar and high-concentration oil stains to avoid clogging the pores.
